### 7.3 Program Number Assignment

Program numbers are given out in groups of hexadecimal 20000000 (decimal 536870912) according to the following chart:

                  0 - 1fffffff   defined by rpc@sun.com
           20000000 - 3fffffff   defined by user
           40000000 - 5fffffff   transient
           60000000 - 7fffffff   reserved
           80000000 - 9fffffff   reserved
           a0000000 - bfffffff   reserved
           c0000000 - dfffffff   reserved
           e0000000 - ffffffff   reserved

The first group is a range of numbers administered by rpc@sun.com and should be identical for all sites. The second range is for applications peculiar to a particular site. This range is intended primarily for debugging new programs. When a site develops an application that might be of general interest, that application should be given an assigned number in the first range. Application developers may apply for blocks of RPC program numbers in the first range by sending electronic mail to "rpc@sun.com". The third group is for applications that generate program numbers dynamically. The final groups are reserved for future use, and should not be used.
